03 yz250f - we just put in a higher compression piston and completely redid the head with new valves, and had the seats machined and all that.. perfect adjustment and so forth. also a jardene (sp?) full pipe put on it.
There is a lag if you pop the throttle.
We raised the needle one spot
bumped the main from 178 to 182
It has a 40 pilot
air screw is 2.25 turns out (stock i think)
Question is.. would putting a 42 pilot in sound unreasonable ?
possibly need a little bigger main as well ?
thoughts on needle position. ?
Pretty soon we are sending the carb to toyko mods but trying to make it usable for now.
